Marine Generators to Power Submergible Transport

The Opportunity

Swiber, a world class company in the offshore industry, offers its global-diverse

clients integrated services within three main business units: offshore construction

services, offshore marine services and engineering services. Swiber was

commissioned to build a huge submergible float-over barge in an Indonesian

shipyard.

Swiber (Newcruz Shipbuilding & Engineering Pte Ltd - Swiber Limited) turned to

Dresser-Rand to power Holmen Pacific and Atlantic because of its vast experience

in the marine industry and its use of the state-of-the-art technology and expansive

resources.

The Solution

Dresser-Rand provided the following equipment to power the Holmen Pacific and Atlantic barges:

Holmen Pacific

Main generators: Three SF480TA-SG Guascor®

gas engines (3 MW); 3 x 1,000kW, 415V/3ph/50Hz

Towing System: 250-ton bollard pull main and emergency lines; bridle recover system.

Holmen Atlantic

Main generators: Three SF360TA-SG Guascor gas

engines (2.25 MW); 3 x 750kW, 415V/3ph/50Hz

Towing System: 200-ton bollard pull main and emergency lines; bridle recover system.

The double cooling system maintains two independent cooling circuits, HT (80ºC) for the cylinder heads, and LT (30ºC) for oil cooler and after cooler with or without an oxidation exhaust catalyst. Such features allow for a number of benefits, including easy operations and maintenance (O&M), power supply in off-the-grid

areas and a heavy-duty, continuous energy source for non-stop maneuvering.
